Description

Technical Field

[0001] The utility model relates to the field of plate processing, in particular to a handheld grinding device. Background Art

[0002] As people's living standards continue to improve, the demand for furniture quality is also getting higher and higher. Furniture panels need to be polished during production, and workers usually use handheld grinders to carefully polish the panels. Most handheld grinders have an additional grip on the side of the handle to facilitate two-handed operation, improve stability during the grinding process, and avoid severe vibration when operating the grinder with one hand. However, depending on the usage environment or user habits, sometimes the handle needs to be held in the left hand and the grip in the right hand, and sometimes the handle needs to be held in the right hand and the grip in the left hand. The grip installation position is difficult to change, which is inconvenient for users. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that under different usage environments or different user habits, sometimes the left hand needs to hold the handle and the right hand needs to hold the grip, and sometimes the right hand needs to hold the handle and the left hand needs to hold the grip. The installation position of the grip is difficult to change, which is inconvenient for users to use.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a handheld grinding device, including a handle and a grinding head arranged at the end of the handle, a button is provided on the surface of the handle, a grip is provided on one side of the handle, the grip is fixedly connected to the handle by a bolt, a through hole for the bolt to pass through is provided in the middle of the handle, a threaded hole matching the bolt is provided at the end of the grip, and a pressing component for pressing the button is provided on the surface of the handle.

[0005] The beneficial effect of the present invention is that by providing the grip, the bolt and the port, the user can adjust the position of the grip on the handle according to the use environment or usage habits, that is, the left side or the right side of the handle, thereby improving the practicality of the grinder.

[0006] As a further improvement of the present invention, the technical problem to be solved is that staff or outsiders may easily accidentally touch the grinder and cause it to start, posing a safety hazard.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the pressing assembly includes a limit plate and a pressure plate hingedly arranged on the surface of the handle, and a first torsion spring for pressing the pressure plate downward is provided at the hinge between the pressure plate and the handle, and a mounting groove is opened at one end of the pressure plate, and the limit plate is rotated inside the mounting groove through a rotating shaft and a second torsion spring for tilting the limit plate is provided at the rotating connection, the outer surface of the limit plate is in contact with the inner surface of the mounting groove, the upper end of the limit plate passes through the outside of the mounting groove, and the lower end of the limit plate is rotatably provided with a roller.

[0008] The beneficial effects of the above improvements are: by setting the pressure plate, the limit plate, the roller and the installation groove, when the limit plate is under the action of the second torsion spring, the angle between the limit plate and the pressure plate is obtuse. At this time, the outer surface of the limit plate abuts against the inside of the installation groove, and the pressure plate cannot be squeezed, which plays a role of safety protection and prevents the staff from accidentally touching the pressure plate squeezing button, causing safety hazards when the grinder is started.

[0009] The utility model further improves the technical solution adopted as follows: a strip groove matching with the limit plate is provided on the surface of the handle, and a groove matching with the roller is provided on the bottom surface of the strip groove.

[0010] The beneficial effects of the above improvements are: by setting the strip grooves and the grooves, on the one hand, the stability of the deflection of the limit plate is guaranteed, and the downward pressure of the pressure plate is guided to avoid twisting and deformation at the hinged connection of the pressure plate; on the other hand, the roller is stuck in the groove to fix the limit plate, thereby ensuring the stability of the pressure plate. During use, when the grinder needs to be stopped, the staff pulls the pressure plate upward to shrink the first torsion spring, and then the limit plate returns to its original state under the action of the second torsion spring. Then the staff releases the pressure plate, so that the limit plate is at an obtuse angle to the pressure plate again, thereby achieving a safety protection effect.

[0011] The utility model further improves the technical solution adopted as follows: the bolt is a hexagon socket bolt, and ports are provided at both ends of the through hole.

[0012] The beneficial effects of the above improvements are: the bolt end is screwed into the port, which effectively prevents the bolt end from being exposed and easily bumped, and improves the aesthetics of the grinder.

[0013] One end of the grip is provided with a docking groove matched with the outer surface of the handle, and the other end of the grip is provided with a rounded corner. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0020] Example 1:

[0021] like Figure 1-4 As shown, a handheld grinding device includes a handle 1 and a grinding head 2 disposed at the end of the handle 1. A button 4 is provided on the surface of the handle 1, and a grip 3 is provided on one side of the handle 1. The grip 3 is fixedly connected to the handle 1 by a bolt 10. A through hole for the bolt 10 is provided in the middle of the handle 1, and a threaded hole 12 is provided at the end of the grip 3 to cooperate with the bolt 10. A pressing component for pressing the button 4 is provided on the surface of the handle 1. The provision of the grip 3, the bolt 10, and the port 11 facilitates the user to adjust the position of the grip 3 on the handle 1 according to the use environment or usage habits, that is, to the left or right side of the handle 1, thereby improving the practicality of the grinder.

[0022] The pressing assembly includes a limit plate 8 and a pressure plate 5 hingedly mounted on the surface of the handle 1. A first torsion spring is provided at the hinged connection between the pressure plate 5 and the handle 1 for pressing the pressure plate 5 downward. A mounting slot 13 is provided at one end of the pressure plate 5. The limit plate 8 is rotatably mounted inside the mounting slot 13 via a rotating shaft, and a second torsion spring is provided at the rotational connection to tilt the limit plate 8. The outer surface of the limit plate 8 contacts the inner surface of the mounting slot 13. The upper end of the limit plate 8 extends out of the mounting slot 13, and a roller 7 is rotatably mounted at the lower end of the limit plate 8. By arranging the pressure plate 5, the limit plate 8, the roller 7, and the mounting slot 13, when the limit plate 8 is acted upon by the second torsion spring, the angle between the limit plate 8 and the pressure plate 5 forms an obtuse angle. At this time, the outer surface of the limit plate 8 abuts against the interior of the mounting slot 13, preventing the pressure plate 5 from being pressed. This serves as a safety protection measure to prevent workers from accidentally touching the pressure plate 5 and squeezing the button 4, which could pose a safety hazard when the grinder is started.

[0023] Example 2:

[0024] Further optimization is made based on the above embodiment: Figure 1-4As shown, the surface of the handle 1 is provided with a strip groove 6 that cooperates with the limit plate 8, and the inner bottom surface of the strip groove 6 is provided with a groove 9 that cooperates with the roller 7. By providing the strip groove 6 and the groove 9, on the one hand, the stability of the deflection of the limit plate 8 is guaranteed, and it plays a guiding role in pressing the pressure plate 5 downward, avoiding torsional deformation at the hinged connection of the pressure plate 5. On the other hand, the roller 7 is inserted into the groove 9 to fix the limit plate 8, thereby ensuring the stability of the pressure plate 5. During use, when it is necessary to stop the grinder, the staff pulls up the pressure plate 5 to make the first torsion spring contract, and then the limit plate 8 returns to its original state under the action of the second torsion spring. Then the staff releases the pressure plate 5, so that the limit plate 8 forms an obtuse angle with the pressure plate 5 again, which plays a safety protection role.

[0025] Example 3:

[0026] Further optimization is made based on the above embodiment: Figure 1-4 As shown, the bolt 10 is a hexagon socket bolt, and ports 11 are provided at both ends of the through hole. The ends of the bolt 10 are screwed into the ports 11, effectively preventing the ends of the bolt 10 from being exposed and easily bumped, and improving the aesthetics of the grinder.

[0027] One end of the grip 3 is provided with a docking groove that matches the outer surface of the handle 1, and the other end of the grip 3 is provided with a rounded corner.
